We have to create sustainable community for the sustenance of life on the planet, else the ecological balance will be disturbed. Our Earth is the only habitable planet. So, spread awareness for saving earth from further deterioration.Eollow 5 R's, i.e. reduce, reuse, recycle, refuse and rethink. Use the resources according to the 'need' and not according to the 'greed'. Care for nature, it will natural resources. care for you.

Conservation means sustainable and optimum.utilisation of resources. We must realise that nature and its resources are not merely ours, They also belong to the future generation. Thus, it is necessary to use the resources more efficiently and reduce wastage. Development of technology, human skill and population control is essential for a long-term sustainability of natural resources.

Conservation

# data[].attributes.body
1. use all renewable resources judiciously.

2. minimise the depletion of natural resources.

3. conserve the varied species.

4. Resources are limited in supply.

5. To stop the degradation and deterioration of resources.

Therefore , it is essential that we:

Sustainable development means development that takes place without damaging th environment. It meets the needs of the present without compromising the needs of futur generations, Therefore, resources should be utilised judiciously so thai after fulfilling our presen requirements, they are also conserved for the future generations. Most of our resources aremite in their supply. Over-use of many valuable resources has led to their degradation or deterioraion quality, for example, soil, land and water resources.

Sustainable development and conservation:-

The actual resources of a country are those which have been thoroughly surveyed and their quantities have been ascertained. The exploration, development and utilisation of an actual resource depends upon the technology available. For exampie, Saudi Arabia has 25.9% of the world oil reserves.

Actual resources

Arctic sea-bed may hold as much as 25% of the world's undiscovered oil and natural gas reserves. By one estimate, 400 million barrels of oil might lie beneath the Arctic sea-bed.

Available resources in a country, which are not fully tapped, are known as potential resource For example, petroleum can be found in old sedimentary rocks of Himalayas or hydroelectricity can be generated by the force of falling water.

Potential resources

Classification based on development of resources:-

# data[].attributes.body
Resources created by human beings to satisfy their needs are known as man-made resources for example, roads, buildings, machines, etc

# data[].attributes.body
Man made resources

# data[].attributes.body
Resources, available from nature in the form of water, minerals, forests, etc, and used by human beings to satisfy their needs, are known as natural resources.

Natural resources

Occasion based on occurrence:-

# data[].attributes.body
Resources, which are obtained from biosphere and have life (irving beings), are known as biotic resources For example, birds, animals, fish, forests, etc., are biotic resources . The biotic resources provide a vaniety of useful products. They have the capacity to reproduce and regenerate . All biotic resources are renewable but some take a long period of time to be renewed, for example, the forests All non-living resources are known as abiotic resources, for example, land, water, minerals, etc . the abiotic resources are not renewable except water which is inexhaustible. These resources are in great demand for the development of various industries and agriculture .

Biotic and abiotic resources

Classification on the basis of origin :-

# data[].attributes.body
Resources, which take millions of years to form or renew, are known as non-renewable resources . They are also known as exhaustible resources as they cannot be renewed. Energy resources, such as/coal, petroleum, natural gas and other minerals are the examples of non-renewable resource.

# data[].attributes.body
Non renewable resources

# data[].attributes.body
Renewable resources are also known as inexhaustible resources. Resources, which can be renewed either naturally or by human efforts, are known as renewable resources, for example, solar energy, air and water. Some of the renewable resources are always available and do not get exhausted by human activities, for example, solar and wind energy. The quality of these resources can be affected by improper usage.

Renewable resources

Classification based on renewability:-

Renewability:- * renewable
* Non - renewable

Occurrence:- * natural
* Man - made

Origin:- * biotic
* Abiotic

Classification of resources.

Basic of classification:-  1. Renewability
2. Origin
3. Occurrence
4. Development

The utilisation of resources depends upon various factors such as:-

Availability of resources

skill of human beings

availability of capital

Availability of water advancement of Technology ( tools, machines ,etc)

Availability of transport and communication facilities , etc.

## china and United States of America (USA) are generating more wind energy than India .

Earlier human civilizations flourished along the river valleys as they use water for irrigating fields . But now the human beings are using water generating energy , irrigation ,navigation and industries etc.

The pygmies of Africa eat edible plants , roots, flowers, fruits and hunt animals.

In acient times, Emphasis was mainly given on satisfying the basic needs , such as food, clothing and shelter which was derived from the natural environment.

Resources:-
We all know that we need air to breathe we need water to drink we need food to eat. We these things from Earth. Hence all the things on the earth which  are necessary for our existence on this planet are known as resources.
